Improvement In HbA1c Research Articles

Impact of smoking cessation on metabolic parameters and renal function in patients with and without diabetes mellitus

Backgroud and objectivesAs patients with diabetes are at a significantly higher risk of cardiovascular diseases than those without diabetes, it is important to gain a clinical understanding of the differential effects of smoking cessation on several risk factors between patients with and without diabetes. Materials and methodsPatients who participated in a smoking cessation program received an assessment of the outcomes of interest. The outcomes were changes in metabolic parameters and renal function from baseline to 6-month follow-up after the smoking cessation program. ResultA total of 1,954 patients joined the smoking cessation program, and 1,381 patients were in the smoking cessation failure (SCF) group and 573 were in the smoking cessation success (SCS) group. The decrease in HbA1c after smoking cessation was only observed in patients with diabetes. Smoking cessation was also associated with a significant decrease in LDL cholesterol in patients with diabetes. In terms of renal function, smoking cessation was associated with an improvement in eGFR, and the trend was similar in patients with and without diabetes. ConclusionSuccessful smoking cessation was associated with improvement in renal function. Moreover, it was associated with improvements in HbA1c and LDL cholesterol in patients with diabetes, despite significant weight gain.

Empagliflozin use in cardiac transplant patients

Objectives: Sodium-glucose transport protein 2 inhibitor |(SGLT2) drugs are used to treat patients with type 2 diabetes. In additions to their beneficial metabolic effects in lowering the glaciated hemoglobin, body weight and blood pressure, these agents have shown favorable and protective effects on the heart and the kidneys. These cardio renal benefits are seen even in people without diabetes. There is little evidence on the safety and efficacy of SGLT2 inhibitors use in cardiac transplant recipients. We wanted to study the cardiac transplant recipients who used Empagliflozin for the treatment of diabetes to evaluate its safety and efficacy in this niche sub group of patients. Method: We retrospectively identified 20 patients on the cardiac transplant recipient register taking Empagliflozin (Jardiance) or Empagliflozin combined with Metformin (Synjardy). We studied the safety and efficacy parameters. Results: Our results show improvement in HBA1c, body weight and stability in serum creatinine. There was no increased risk of genitourinary infection, hypoglycemia or diabetic ketoacidosis. Conclusion: While we need larger studies in cardiac transplant patients taking Empagliflozin, our small study provides assurance that Empagliflozin is safe to use in cardiac transplant recipients.

Effectiveness and safety of insulin glargine 300 U/mL in insulin-naïve individuals according to diabetes duration: Results from the REALI European pooled data analysis.

To evaluate the effectiveness and safety of insulin glargine 300 U/mL (Gla-300) initiation according to diabetes duration (DD). We analysed patient-level data from 2381 insulin-naïve individuals with type 2 diabetes (T2D), of whom 2349 (98.7%) were treated with Gla-300 for 24 weeks. Of the 2381 participants, 1048 (44.0%) had a DD of less than 8 years and 1333 (56.0%) had a DD of 8 years or longer. We further analysed the subgroups of participants having a DD of less than 4 years (N = 450), 4-8 years (N = 598), 8-12 years (N = 627) and 12 years or longer (N = 706). Mean ± standard deviation age was 60.2 ± 9.0 years in participants with a DD less than 8 years and 64.2 ± 8.8 years in those with a DD of 8 years or longer. At 24 weeks of Gla-300 therapy, HbA1c improved with a least-squares (LS) mean change from baseline of -1.88% (95% confidence interval [CI], -1.95 to -1.80) and -1.71% (95% CI, -1.77 to -1.65), respectively, resulting in a LS mean difference between groups of 0.17% (95% CI, 0.07 to 0.26; P = .0005). In the subgroup analysis, LS mean HbA1c reduction from baseline to week 24 was highest in participants with a DD of less than 4 years and lowest in participants with a DD of 12 years or longer. Overall, incidences of symptomatic and severe hypoglycaemia were low, irrespective of DD, without body weight changes. Gla-300 was effective and safe in insulin-naïve individuals with T2D, regardless of DD. Improvement in HbA1c was greater when Gla-300 was initiated in participants with a DD of less than 4 years, although the difference between the groups was modest.

Five-year outcomes of a holistic programme for managing early chronic kidney disease in primary care.

Holistic Approach in Lowering and Tracking Chronic Kidney Disease (HALT-CKD) is a nationwide programme that was introduced in 2017 to combat CKD in Singapore. This study aims to evaluate outcomes of the HALT-CKD programme and identify factors influencing disease progression among early CKD patients. We conducted a retrospective cohort study involving adult patients aged 21 to 80 with CKD stages G1-G3A, recruited from 5 Singapore polyclinics between 2017 and 2018. The primary outcome-time to progression to advanced CKD (G3B-G5)-was tracked until March 2023, based on patients' last known serum creatinine levels. Descriptive statistics and Cox regression were used. Patients who followed up with other institutions, were deceased or defaulted without developing (or experiencing) the outcome were censored. We studied 3800 patients (mean age: 61.9 years) for a median of 4.7 years. Among them, 12.6% developed advanced CKD despite statistically significant improvements in HbA1c, blood pressure and albuminuria levels. Increasing age, female sex, clinic, baseline creatinine, diastolic blood pressure and HbA1c significantly shortened time to CKD progression. Macro-albuminuria at baseline (hazard ratio [HR] 1.77, 95% confidence interval [CI] 1.19- 2.61) and at analysis (HR 2.22, 95% CI 1.55-3.19) significantly accelerated advanced CKD progression. Patients who had their angiotensin-converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB) dose reduced or discontinued progressed to advanced CKD earlier (HR 1.92, 95% CI 1.50-2.45). Counselling and sodium-glucose cotransporter-2 inhibitor (SGLT2i) use did not significantly delay CKD progression. Maintaining optimal ACEi/ARB dosage is essential to delay CKD progression. Premature cessation or reduction of this dosage should be discouraged. Further research on counselling and SGLT2i use in early CKD is needed to address the growing burden of CKD.

7636 Once-weekly Insulin Icodec versus Once-daily Long-acting Insulins for Type 2 Diabetes Mellitus: Systematic Review and Meta-analysis

Abstract Disclosure: S.G. Ribeiro: None. M.P. Chavez: None. L.C. Hespanhol: None. A.B. Neto: None. M.D. Gauza: None. E. Paqualotto: None. C.A. Balieiro: None. C.C. Padovese: None. J.R. Sa: None. Background: Insulin icodec is a novel, long-acting, once-weekly basal insulin analog. Its comparative efficacy and safety with basal once-daily insulins in type 2 diabetes mellittus is uncertain. Objective: Evaluate potential efficacy, benefits and risks associated with icodec compared to once-daily basal insulin analogs (degludec or glargine). Methods: We systematically searched PubMed, Cochrane, and Embase for randomized controlled trials (RCTs) published until June 2023 comparing icodec versus long-acting insulin analogs (degludec and glargine) in type 2 diabetes mellitus (T2DM) with at least 12 weeks of follow-up. Binary endpoints were assessed with risk ratios (RRs) and continuous endpoints were compared using weighted mean differences (WMDs), with 95% confidence intervals (CIs). The protocol was registered in PROSPERO (CRD42023452468). Results: A total of seven RCTs and 3,286 patients with T2DM were included, of whom 1,509 (60.6%) received icodec treatment. The follow-up period ranged from 16 to 78 weeks. Compared with once-daily basal insulin analogs, icodec led to a greater improvement in HbA1c (WMD -0.15%; 95% CI -0.21, -0.10; p<0.0001; I²=0%) and time in range (TIR) (WMD 2.83%; 95%CI 0.94; 4.71; p=0.003; I2=22%). Body weight was increased with icodec treatment (WMD 0.78 Kg; 95%CI 0.42, 1.15; p<0.01; I2=86%). There was also a higher rate of injection site reactions (RR 1.89; 95%CI 1.12, 3.18; p=0.016; I²=0%) and nasopharyngitis (RR 1.94; 95%CI 1.11, 3.38; p=0.020; I²=0%) in the icodec group, compared with once-daily regimens. There was no significant difference between groups in fasting plasma glucose. Conclusions: In this meta-analysis of RCTs, insulin icodec led to better control of HbA1c and TIR as compared with once-daily insulin regimens, albeit with increased weight gain and a higher rate of injection site reaction in the Icodec group.

6971 Effects of the Hybrid Closed-loop System in Pediatric-Onset Type 1 Diabetes

Abstract Disclosure: H. Woo: None. J. Yoo: None. S. Shin: None. Y. Lee: None. H. Kim: None. M. Gu: None. J. Kim: None. J. Kim: None. C. Shin: None. Y. Lee: None. Purpose: We evaluated the effectiveness and limitations of the MiniMedTM 770G, a hybrid closed-loop (HCL) system which adjusts basal insulin every five minutes using continuous glucose monitoring (CGM) data, for glycemic control in pediatric-onset type 1 diabetes (T1D) in South Korea. Methods: We enrolled 20 patients (10 boys and 10 girls) who had been using the 770G pump for over three months, initiating its use between February 2022 and May 2023. Prior to this, they were CGM users and were followed for over a year post T1D diagnosis. Clinical and biochemical data, along with CGM metrics such as time in range (TIR), time below range (TBR), time above range (TAR), and coefficient of variation (CV), were analyzed. Additionally, the percentage of SmartGuard Auto Mode system usage was collected. Results: The median age at the start of 770G was 13.97 years (IQR 11.24–17.86), with a median of 6.5 years of duration of type 1 diabetes. After utilizing the 770G pump (n=20), TIR, TAR, and CV improved over the year (P<0.05). Patients utilizing Auto Mode over 85% of the time exhibited significant improvements in HbA1c (P=0.02), TIR (P=0.04), CV (P<0.01), and TAR 250 (P=0.02), in contrast to those who used Auto Mode 85% or less. Hyperglycemia and lack of calibration contributed to over 50% of the exits from Auto Mode. Conclusions: The implementation of HCL in adolescents and young adults with T1D enhanced glycemic control over one year. Educating patients on sustained Auto Mode use without interruptions is crucial. Presentation: 6/2/2024

5180 Atypical Presentation of Type 2 Diabetes Mellitus in a 72Year Old Caucasian Male with Hemoglobin J-Baltimore Variant: A Case Report

Abstract Disclosure: C. Muojieje: None. M. Luzuriaga: None. Objective: This case report discusses the unusual manifestation of Type 2 Diabetes Mellitus (T2DM) in a 72-year-old Caucasian male possessing a rare Hemoglobin variant, Hemoglobin J-Baltimore. It emphasizes the importance of recognizing how hemoglobin variants can impact HbA1c measurements. Alternative markers, such as fructosamine and HbA1c measurement using turbidimetric inhibition immunoassay (TINIA), are discussed as potential tools for a more precise assessment of glycemic control. Furthermore, it accentuates the effectiveness of tailored treatment strategies in such cases. Methods: A 72-year-old Caucasian male with a history of T2DM was referred to an endocrinology clinic due to substantial discordance between the blood glucose (BG) values when self-monitoring and HbA1c. The patient was diagnosed with T2DM a decade ago due to fasting hyperglycemia. His HbA1c levels had remained within normal range. He exhibited signs of diabetic nephropathy with moderately increased albuminuria. He was never prescribed an oral hypoglycemic agent. He reported polyuria, weight loss, and fatigue, prompting him to monitor his BG at home twice daily, revealing readings > 200 mg/dl. HbA1c measurement using high-performance liquid chromatography (HPLC) was 4.8%. His fasting plasma glucose was 190 mg/dl, and fructosamine levels were 292 umol/L (205 - 285 umol/L). An HbA1c level via TINIA was 6.4%. Hemoglobin electrophoresis unveiled the presence of Hemoglobin J-Baltimore. We started metformin, resulting in an improvement in HbA1c from 6.4% to 5.8%. Fructosamine levels improved from 292 umol/L to 210 umol/L. Fasting blood glucose remained > 150 mg/dl. Dulaglutide was introduced. Follow-up analysis showed an improvement in FBS to < 120 mg/dl. HbA1c remained unchanged at 5.9%. Conclusion: The significance of hemoglobin variants, exemplified by Hemoglobin J-Baltimore, cannot be overstated in the context of patients with T2DM, especially within populations where these variants are uncommon. This case underscores the need for a nuanced approach to glycemic control assessment in such individuals. The utilization of alternative markers, such as HbA1c values obtained through TINIA, emerges as a valuable strategy. The role of continuous glucose monitoring (CGM) is crucial, providing real-time and comprehensive data, which enhances the quality of care and contributes to more tailored and effective treatment strategies.

7431 Non-Insulin Treatment of Type 1 Diabetes Mellitus: The Power of GLP-1 and GLP-1/GIP RA

Abstract Disclosure: J. Ferri-Guerra: None. E. Kasper-Guerra: None. O. Abdulhussein: None. G. Madrigal Loria: None. J. Ambalavanan: None. K. Zhou: None. Background: Insulin is the mainstay of treatment of patients with type 1 diabetes mellitus (T1D). However, patients with T1D can also potentially benefit from adjunctive therapies such as GLP-1 receptor agonists or GLP-1/GIP receptor agonists, especially when obesity and elevated cardiovascular risk are present. Case 1: A 64-year-old male with severe coronary artery disease requiring revascularization and obesity with T1D has been wearing a pump for insulin delivery since the age of 43, started on closed loop system Control IQ with Tandem in April 2022. In December 2022, patient had myocardial infarction. At that time, Hba1c was elevated at 7.6% and BMI was elevated at 32.5 kg/m2, and patient was considered a good candidate for tirzepatide, which was prescribed. The tirzepatide dose was slowly increased, up to 10 mg weekly. The new therapy resulted in loss of 17 kg (20.1% decrease of body weight) with only some mild nausea. There was an improvement in HbA1c to 7.1% and a dramatic reduction in daily average insulin use from 90 units to 52 units. Case 2: A 59-year-old female with obesity and T1D diagnosed at the age of 8 had been wearing insulin pump, Medtronic 670G in manual mode, for insulin delivery for the past few years with poor glycemic control. In August 2021, patient was prescribed semaglutide for post prandial hyperglycemia and obesity management (BMI at 31.6kg/m2). Since being on the medication, she lost 12kg (16.8% decrease in body weight), despite being on the lowest dose of 0.25 mg (maximum tolerated). Her HbA1c has improved from 8.2% when therapy was initiated, to 7% with just the introduction of semaglutide to her insulin regimen. Conclusion: Although insulin is a required therapy for patients with T1D, adjunctive therapies may improve glycemic control, reduce insulin requirements and promote weight loss. GLP-1 and dual GLP-1/GIP receptor agonists should be considered for these patients. Presentation: 6/1/2024

8336 Glycemic Control and Associated Factors During Transition in Youths with Childhood-onset Type 2 Diabetes Mellitus

Abstract Disclosure: J. Yoo: None. H. Woo: None. M. Gu: None. J. Kim: None. Y. Lee: None. C. Shin: None. Y. Lee: None. Background: Childhood-onset type 2 diabetes has increased risk of early diabetes-related complications due to accelerated loss of pancreatic beta cell function. However, no second-choice anti-diabetic drug(such as GLP1 receptor agonists and SGLT2 inhibitors), other than metformin and insulin, is approved to be administered in pediatric patients with type 2 diabetes in South Korea. This study aimed to describe microvascular complications (nephropathy and eye disease) of youths with childhood-onset type 2 diabetes, investigate trends of glycemic control of patients and associated factors across transition period, and analyze change in glycemic control after adding 2nd-choice drug. Method: Among the patients who were treated for type 2 diabetes at Seoul National University Hospital since 2001, 84 patients who were diagnosed under age 18 and reached at age 20 or more on July, 2023 were included. Data of HbA1c, diabetes duration, administered medication, and diabetic complications were collected. Changes in HbA1c from 19 to 22 years of age (transition period) were investigated, and sex, age at diagnosis, and glycemic control at age 19 were analyzed as associated factors. Result: The average age of diagnosis and last follow-up was 14 years and 24.9 years respectively, and the median duration of diabetes was 9.6 years. At the last follow-up, complications developed in 28 patients (33.7%), and the prevalence was 25.3% for nephropathy and 20.6% for eye disease. At the occurrence of complications, the median diabetes duration was 6.2 years for microalbuminuria and 11.3 years for ophthalmic complications. During the transition period, HbA1c showed a significant decline from 8.3% to 7.7% (p=0.007). During this phase HbA1c decreased more significantly in the female (vs. male), in the patients with diagnostic age <15 years (vs. >15 years old), and patients with HbA1c 7% or above at 19-year-old visit(vs. < 7%). During entire follow-up, 59 patients (70%) received diabetes drugs other than metformin and insulin. At diagnosis, the proportion of patients treated with insulin accounted for 55%. At last visit, only few patients were maintained with metformin alone, and most patients required insulin or 2nd-choice antidiabetic drug. Analysis of HbA1c changes in 59 patients with the addition of 2nd-choice drug showed a decrease to 8.5% after 1 year (p=0.006) and to 8.1% at the last visit(p=0.017). Conclusion: Diabetic complications were observed in one-thirds of youths with type 2 diabetes at last follow-up in this study. Glycemic control during transition period to adulthood showed improvement, and factors that influence HbA1c improvement included female, younger age at diagnosis, and better glycemic control at age 19. There is a need to lower the insurance age criteria of South Korea for 2nd-choice antidiabetic drugs, considering that glycemic control significantly improved after adding the 2nd-choice drugs.

A comparison of the safety and effectiveness of insulin aspart with other bolus insulins in women with pre-existing Type 1 diabetes during pregnancy: A post hoc analysis of a prospective cohort study.

The safety and efficacy of insulin analogue insulin aspart (IAsp) have been demonstrated in a randomised clinical trial in pregnant women with Type 1 diabetes (T1D), and IAsp is widely used during pregnancy. The aim of this study was to assess glycaemic control and safety of IAsp versus other bolus insulins in Type 1 diabetic pregnancy in a real-world setting. This was a post hoc analysis of a prospective cohort study of 1840 pregnant women with T1D, treated with IAsp (n = 1434) or other bolus insulins (n = 406) in the Diabetes Pregnancy Registry. The primary (composite) outcome was the proportion of pregnancies resulting in major congenital malformations or perinatal or neonatal death. Secondary outcomes included all HbA1c values measured immediately before and during pregnancy and major hypoglycaemia, as well as abortion, pre-eclampsia, pre-term delivery, large for gestational age at birth, stillbirth and fetal malformations. There were no significant differences found in any of the pregnancy outcomes between treatment with IAsp and other bolus insulins in either the crude or propensity score-adjusted analyses. However, maternal HbA1c was lower in the IAsp group at the end of the third trimester (adjusted difference, -0.16% point [95% CI -0.28;-0.05]; -1.8 mmol/mol [95% CI -3.1;-0.6]; p = 0.0046). No significant differences in safety or pregnancy outcomes were demonstrated when comparing treatment with IAsp versus other bolus insulins in women with T1D during pregnancy. The observed improvement in HbA1c with IAsp in late pregnancy should be confirmed in other studies.

A post-hoc pooled analysis to evaluate efficacy and safety of insulin glargine 300 U/mL in insulin-naïve people with type 2 diabetes with/without prior use of glucagon-like peptide-1 receptor agonist therapy

AimsTo evaluate treatment advancement with insulin glargine 300 U/mL (Gla-300), with or without prior glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy in type 2 diabetes (T2D). MethodsEfficacy and safety outcomes of insulin-naïve patients intensifying with Gla-300, with/without prior GLP-1 RA therapy, were evaluated in three analyses (N = 3562): a pooled analysis of seven interventional studies, a subanalysis comparing participants who stopped GLP-1 RA therapy and initiated Gla-300 with those who received add-on Gla-300, and an expanded analysis including two observational studies. ResultsGlycaemic outcomes, including HbA1c improvement and fasting plasma glucose, were similar between groups with/without prior GLP-1 RA use. HbA1c least squares mean change from baseline was − 1.7 % and − 1.6 % with and without prior GLP-1 RA, respectively. Glycaemic outcomes were similar between participants who stopped GLP-1 RA therapy when initiating Gla-300 and those who received add-on Gla-300, although more participants receiving add-on Gla-300 achieved HbA1c targets. The expanded analysis yielded similar results. Incidence of hypoglycaemia was low with no clinically relevant weight changes in all analyses. ConclusionsTreatment advancement with Gla-300 in patients with T2D, with/without prior GLP-1 RA therapy, improved glycaemic outcomes with no relevant impact on weight, while maintaining a low hypoglycaemia risk.

Semaglutide for the management of diabesity: The real-world experience.

Diabesity (diabetes as a consequence of obesity) has emerged as a huge healthcare challenge across the globe due to the obesity pandemic. Judicious use of antidiabetic medications including semaglutide is important for optimal management of diabesity as proven by multiple randomized controlled trials. However, more real-world data is needed to further improve the clinical practice. To study the real-world benefits and side effects of using semaglutide to manage patients with diabesity. We evaluated the efficacy and safety of semaglutide use in managing patients with diabesity in a large academic hospital in the United States. Several parameters were analyzed including demographic information, the data on improvement of glycated hemoglobin (HbA1c), body weight reduction and insulin dose adjustments at 6 and 12 months, as well as at the latest follow up period. The data was obtained from the electronic patient records between January 2019 to May 2023. 106 patients (56 males) with type 2 diabetes mellitus (T2DM), mean age 60.8 ± 11.2 years, mean durations of T2DM 12.4 ± 7.2 years and mean semaglutide treatment for 2.6 ± 1.1 years were included. Semaglutide treatment was associated with significant improvement in diabesity outcomes such as mean weight reductions from baseline 110.4 ± 24.6 kg to 99.9 ± 24.9 kg at 12 months and 96.8 ± 22.9 kg at latest follow up and HbA1c improvement from baseline of 82 ± 21 mmol/mol to 67 ± 20 at 12 months and 71 ± 23 mmol/mol at the latest follow up. An insulin dose reduction from mean baseline of 95 ± 74 units to 76.5 ± 56.2 units was also observed at the latest follow up. Side effects were mild and mainly gastrointestinal like bloating and nausea improving with prolonged use of semaglutide. Semaglutide treatment is associated with significant improvement in diabesity outcomes such as reduction in body weight, HbA1c and insulin doses without major adverse effects. Reviews of largescale real-world data are expected to inform better clinical practice decision making to improve the care of patients with diabesity.

NOVOS ANTIDIABÉTICOS E PERSPECTIVAS NO MANEJO DA HIPERGLICEMIA CRÔNICA

The management of type 2 diabetes mellitus (T2DM) has evolved with the emergence of new oral and subcutaneous antidiabetic agents, which aim not only at glycemic control but also at the prevention of systemic complications. This study reviews the effects of new classes of hypoglycemic agents, such as SGLT-2 inhibitors, GLP-1 agonists, and insulin analogs, on chronic hyperglycemia control and complication prevention. An integrative literature review was conducted using the PubMed database, with articles published between 2019 and 2024, selected using the search key: ‘novel antidiabetic drugs’ OR ‘SGLT-2 inhibitors’ AND ‘chronic hyperglycemia’. Clinical trials and systematic reviews with full text in English were included. SGLT-2 inhibitors were found to be effective in reducing cardiovascular and renal events, along with a significant improvement in glycemic control. GLP-1 agonists and new combination therapies also demonstrated reductions in HbA1c levels and improvements in therisk profile for complications such as cardiovascular disease, diabetic nephropathy, and retinopathy. The inclusion of new devices, such as smart pens, has also contributed to individualized patient management. The introduction of new antidiabetic agents, with innovative mechanisms of action, has brought a significant advancement in the treatment of T2DM patients, aiding in complication prevention and optimizing glycemic control. The continued evolution of these therapies promises new perspectives in disease management.

The Supporting Emerging Adults With Diabetes (SEAD) Program: An Adult-Based Real-World Clinical Model That Improves Hospitalizations, Diabetes Technology Uptake, and Glycemic Outcomes in Underserved Young Adults With Type 1 Diabetes.

Underserved young adults (YA) with type 1 diabetes (T1D) experience the worst outcomes across the life span. We developed and integrated the Supporting Emerging Adults with Diabetes (SEAD) program into routine endocrinology care to address unmet social and medical challenges. This study was designed as a longitudinal cohort study, with prospective data collection over 4 years on YA in SEAD compared with usual endocrine care. We used propensity-weighted analysis to account for differences in baseline characteristics, and multivariate regression and Cox proportional hazard models to evaluate change in outcomes over time. Primary outcomes included incidence of hospitalizations, diabetes technology uptake, and annual change in HbA1c levels. We included 497 YA with T1D in SEAD (n = 332) and usual endocrine care (n = 165); mean age 25 years, 27% non-Hispanic Black, 46% Hispanic, 49% public insurance, mean HbA1c 9.2%. Comparing YA in SEAD versus usual care, 1) incidence of hospitalizations was reduced by 64% for baseline HbA1c >9% (HR 0.36 [0.13, 0.98]) and 74% for publicly insured (HR 0.26 [0.07, 0.90]); 2) automated insulin delivery uptake was 1.5-times higher (HR 1.51 [0.83, 2.77]); and 3) HbA1c improvement was greater (SEAD, -0.37% per year [-0.59, -0.15]; usual care, -0.26% per year [-0.58, 0.05]). SEAD meaningfully improves clinical outcomes in underserved YA with T1D, especially for publicly insured and high baseline HbA1c levels. Early intervention for at-risk YA with T1D as they enter adult care could reduce inequity in short and long-term outcomes.

HbA1c and Liver Fat Following 16 Weeks of Fasted versus Fed Exercise Training in Adults with Type 2 Diabetes.

Exercise-nutrient timing is of interest for people with type 2 diabetes (T2D) as a potential method to optimize glycemic control. However, the optimal nutritional environment for exercise is not well understood over the long term. The Fasted Exercise for Type 2 Diabetes (FED) Trial compared 16 weeks of fasted versus postprandial morning exercise on glycated hemoglobin (HbA1c) and liver proton density fat fraction (PDFF). Twenty adults with T2D were recruited and randomized to complete exercise after an overnight fast versus after their morning meal. Participants walked three mornings per week, progressing to 180 minutes per week over 16 weeks. Groups were balanced with 5 males and 5 females each. Sixteen participants completed the trial (8 in each group, 50% female). Age, HbA1c, and PDFF were 59.8 ± 9.0 years, 7.2 ± 0.7%, and 9.3 ± 4.1%, respectively. On average, both groups completed 98% of their walking sessions but there was no change in HbA1c (-0.2%, p = 0.588). However, one participant from each group had changes in their glucose lowering medication during the trial and, when excluded, the fasted training group had greater improvements in HbA1c compared to the postprandial group (-0.3% versus 0.0%, p = 0.033). There was no difference in changes in liver PDFF between groups (-1.6% versus 0.3%, p = 0.221) but visceral fat and intramuscular fat decreased to a greater extent following fasted exercise. Although our study had a small sample size, it suggests that exercise after an overnight fast can have high adherence and represents an option for people with T2D to improve longer-term indicators of glycemia and ectopic fat depots.

The effect of vitamin D supplementation on markers of insulin resistance in women with polycystic ovarian syndrome: a systematic review.

Insulin resistance (IR) is a common pathology in women with polycystic ovarian syndrome (PCOS) involved in increased rates of cardiometabolic disease such as diabetes and cardiovascular disease. Low serum vitamin D is often associated with insulin resistance but there is no consensus on whether vitamin D supplementation can ameliorate markers of IR in PCOS. We assessed evidence on the effects of vitamin D supplementation (≥ 1000 IU/day), without the use of additional supplements or other pharmacological treatments known to affect IR, on markers of IR and glycemic control in women with PCOS. A systematic search was conducted using PubMed, Medline and Web of Science databases from January 2000 up to November 2023. Randomized controlled trials that assessed the effects of vitamin D supplementation in women with PCOS, on fasting glucose, fasting insulin, glycated haemoglobin (HbA1c) or homeostatic model assessment for insulin resistance (HOMA-IR) were included. 9 studies were identified. Study populations ranged from 28 to 180 participants, with mean ages ranging from 22 to 30 years. Daily vitamin D doses ranged from 1714-12,000 IU. Of the included studies, 3 reported statistically significant reductions in fasting glucose, 2 reported reductions in fasting insulin, 2 reported reductions in HOMA-IR, none reported reductions in HbA1c and 5 reported no differences in any of the relevant outcomes. In conclusion, in RCTs of vitamin D supplementation in women with PCOS, the majority of studies do not report statistically significant improvements in fasting glucose, fasting insulin, HbA1c or HOMA-IR. However, as a minority of studies report some statistically significant results, further investigation may be warranted. PROSPERO ID: CRD42023486144.

Safety and Effectiveness of Concomitant iGlarLixi and SGLT-2i Use in People with T2D During Ramadan Fasting: A SoliRam Study Sub-analysis.

The aim of this work was to assess the safety and effectiveness of concomitant iGlarLixi and sodium-glucose co-transporter-2 inhibitors (SGLT-2i) use in adults with type 2 diabetes (T2D) who fasted during Ramadan. Of the 420 eligible participants from the SoliRam study, 174 were using SGLT-2i in addition to iGlarLixi and 246 were not using SGLT-2i, referred to as SGLT-2i user and non-user, respectively. The primary endpoint was the proportion of participants experiencing ≥ 1 severe and/or symptomatic documented (< 70mg/dl [< 3.9mmol/l]) hypoglycemia. More than 50% of participants in both groups were male. The mean weight, glycated hemoglobin (HbA1c), and fasting plasma glucose (FPG) were similar in both groups. Approximately half of participants in the SGLT-2i-user group and ~ 25% participants in the SGLT-2i-non-user group were on two oral anti-hyperglycemic drugs (OADs), whereas ~ 20% in the SGLT-2i-user group and ~ 1% of participants in the SGLT-2i-non-user group were on three OADs in addition to iGlarLixi. Around 35% and 55% of participants in the SGLT-2i-user and SGLT-2i-non-user groups, respectively, were taking concurrent sulphonylureas. About 97% of participants in both groups were able to fast for ≥ 25days. The incidence of primary endpoint was low in both groups; SGLT-2i user: 0.6%, 4.2%, and 0.6% and SGLT-2i-non-user: 1.3%, 0.9% and 0% during pre-Ramadan, Ramadan, and post-Ramadan period, respectively. The incidence of severe and/or symptomatic documented (< 54mg/dl [< 3.0mmol/l]) hypoglycemia events was also low throughout the study, including during Ramadan. No severe hypoglycemia occurred during Ramadan in either group. Improvements in HbA1c and FPG, with a small reduction in weight, were observed from pre- to post-Ramadan in both groups. No serious adverse event was reported in either group. Concomitant iGlarLixi and SGLT-2i therapy with or without other OADs was demonstrated to be safe in adults with T2D during Ramadan fast, with a low risk of hypoglycemia and improvements in glycemic outcomes.

Effect of patient-centered self-management intervention on glycemic control, self-efficacy, and self-care behaviors in South Asian adults with type 2 diabetes mellitus: A multicenter randomized controlled trial.

This study aimed to test the efficacy of patient-centered self-management intervention (PACE-SMI) to improve HbA1c, self-efficacy, and self-care behaviors in adults with type 2 diabetes mellitus (T2DM). In this multicenter, parallel two-arm randomized controlled trial, 612 adults with T2DM and HbA1c ≥ 7% were enrolled and assigned to the control group (n = 310) and the intervention group (n = 302) using stratified permuted block randomization. The control group received usual care, whereas the intervention group received usual care plus nurse-led, theory-driven, culturally tailored PACE-SMI, comprising eight weekly sessions of individualized education, counseling, behavioral training, and home visit. Outcomes were assessed at baseline, postintervention, and 3 months follow-up. Data at 3 months were provided by 583 participants (control: n = 295, intervention: n = 288). Per-protocol analysis showed that the intervention group had a lower mean HbA1c (8.49% [standard deviation (SD), 1.58]) than the control group (8.74% [SD, 1.62]), with small yet statistically significant mean difference of 0.25% (95% confidence interval [CI], -0.01 to 0.51; Cohen's d = 0.16; p = 0.03). Self-efficacy and self-care behaviors significantly improved in the intervention group (116.89 [SD, 25.50] and 70.01 [SD, 17.97]) compared to the control group (75.43 [SD, 18.99] and 51.54 [SD, 12.04]), with mean differences of 41.48 (95% CI, 37.83-45.13; Cohen's d = 1.84; p < 0.0001) and 18.56 (95% CI, 16.08-21.04; Cohen's d = 1.22; p < 0.0001), respectively. Linear regression analysis indicated the effect of PACE-SMI on HbA1c was significantly mediated by improvements in self-efficacy and self-care behaviors (R2 = 0.232, p < 0.001). PACE-SMI led to modest but significant improvement in HbA1c and substantial enhancements in self-efficacy and self-care behaviors in adults with T2DM.

The effectiveness of 0.5 mg and 1mg of semaglutide in patients with type two diabetes and predictors of response: a retrospective cohort study.

Semaglutide is a glucagon-like peptide-1 receptor agonists (GLP-1-RAs) approved for the treatment of type 2 diabetes mellitus (T2DM) at doses up to 1 mg. The results from randomized control trials and real-world studies revealed that weekly semaglutide was associated with significant improvements in HbA1c and body weight. To our knowledge, no study assessed the effectiveness of using semaglutide for patients with T2DM in the Saudi population. We aim to assess the effectiveness of once weekly SC 0.5 and 1 mg of semaglutide on HbA1c and weight reduction in patients with T2DM in the Saudi population within 12 months of use, evaluate the predictors of response, and compare the effect of the two doses. This is a retrospective cohort study conducted at Security Force Hospital in Riyadh, Saudi Arabia. Using electronic medical records of patients with type two diabetes who received semaglutide 0.5 or 1 mg for a total duration of at least 12 months of use. Within the study period of semaglutide use, HbA1c significantly decreased from baseline by -2.1% (-2.3 to -1.91, 95% CI) (P <0.001). While the mean change in weight was -6.19kg (-6.66 to -5.72, 95% CI) (P<0.001). Moreover, BMI, FBG, total cholesterol, LDL, and TG all decreased significantly from baseline (p<0.001). When comparing the sub-groups of 0.5 and 1 mg doses, although results were numerically favorable of 1 mg, there were no statistically significant differences in HbA1c % (-2.1 ± 1.8 vs. -2.1 ± 1.9, p-value= 0.934, respectively), and weight (-6.1 ± 5 vs. -6.2 ± 4.4kg, p-value=0.837, respectively). Significant predictors of HbA1c reduction were the duration of DM, baseline HbA1c, and insulin therapy. While the significant predictor for weight reduction was insulin therapy. This study is document the effectiveness of once-weekly SC semaglutide on glycemic control and weight loss in real-world practice. We recommend a starting goal dose of 0.5 mg and gradual increase of dose based individual patient response. further studies are needed to assess the effectiveness and tolerability of various semagltude doses.
